## Manual flight

{% stepper %}
{% step %}
**Pre-flight check**

Make sure, that:

* propellers are facing correct directions and are tightened firmly.
* FPV battery is charged.
* there is no visible damage to FPV or loose parts.
* all other necessary devices are charged and are working properly.
  {% endstep %}

{% step %}
**Pair devices**

1. Make sure, that **controller sticks are in their default position**. Both sticks must be **in the center position**.
2. Check if the drone is **disarmed**.
3. **Plug in FPV battery**, which will automatically turn on FPV.
4. **Wait until FPV initializes itself**. Successfully initialized drone with GPS lock is signalized by LEDs on the GPS module flashing green.

{% hint style="info" %}
You can take a look on all GPS LEDs meanings in the following documentation:\
<https://ardupilot.org/copter/docs/common-leds-pixhawk.html>
{% endhint %}
{% endstep %}

{% step %}
**In flight controls**

{% hint style="info" %}
We recommend to move the sticks **very gently** at first. By doing so you can prevent sudden and unexpected changes in movement of the drone and possible crashes.
{% endhint %}

{% hint style="info" %}
Changing default flight modes can be done through GCS in `Vehicle Setup/Flight Modes` by changing `Flight Mode` 1 to 6.
{% endhint %}

**Emergency stop**

Emergency stop is designed to immediately stop all motors whether the aircraft is flying or not. Its purpose is to prevent damage, injury, or further operational issues.

**Emergency stop can be activated anytime.**

To activate emergency stop **push buttons ( 9 )** and **( 10 )** simultaneously.
{% endstep %}

{% step %}
**Arming and takeoff**

{% hint style="info" %}
It is recommended to take off in `Loiter` flight mode. `Loiter` mode **maintains the current location, heading and altitude** automatically, which makes it suitable for beginner operators.

To use `Loiter` mode, your GPS has to be successfully connected to satellite network. (signalized by **flashing green** LEDs when FPV is disarmed)
{% endhint %}

1. Arm the drone by pressing button **( 3 )**.
2. To take off with the drone, slowly move the throttle stick up, until the drone starts slowly moving up in the air.
   {% endstep %}

{% step %}
**Landing and disarming**

{% hint style="warning" %}
Always check your landing area for obstacles or uneven terrain to avoid damaging or crashing the drone.
{% endhint %}

1. Switch your drone to `Loiter` mode (optional, although recommended for beginners)
2. Position your aircraft about 10 m above the desired landing area.
3. Gently decrease your throttle using throttle stick until your drone starts slowly descending and hold your throttle stick on the same level.
4. When the drone touches the ground, disarm it by **pushing** **buttons ( 9 )** and **( 10 )** simultaneously.
5. Wait until the propellers stop spinning.

{% hint style="warning" %}
**Always keep your distance from landing or armed drone. Rotating propellers may cause serious injuries.**
{% endhint %}
{% endstep %}

{% step %}
**Post-flight**

{% hint style="warning" %}
**Turn off video recording** before disconnecting or removing the battery. If the battery is unplugged while recording, the video file will become corrupted.

In some cases, video may be repaired by using following tool:\

{% endhint %}

If FPV is disarmed, turn it off by unplugging the battery.
{% endstep %}
{% endstepper %}
